David Given 25b6712e63 Rework all the ackbuilder scripts not to use wildcards, because we can't expand 
them without luaposix, which isn't available (easily) on OSX or Windows.

George Koehler 7ab4794a05 Reduce clang warnings from ncg 
If a .c file included "types.h" before "mach.h", then it missed the
declaration of mach_option().  Fix by adding "xmach.h".

Fix mach/powerpc/ncg/mach.h and mach/vc4/ncg/mach.h to use the correct
type in their printf() format strings.

George Koehler 1faff418ec Teach some ncg machines to use .data8 
This turns EM `con 5000000000I8` into assembly `.data8 5000000000` for
machines i386, i80, i86, m68020, powerpc, vc4.  These are the only ncg
machines in our build.

i80 and i86 get con_mult(sz) for sz == 4 and sz == 8.  The other
machines only get sz == 8, because they have 4-byte words, and ncg
only calls con_mult(sz) when sz is greater than the word size.  The
tab "\t" after .data4 or .data8 is like the tabs in the con_*() macros
of mach/*/ncg/mach.h.

i86 now uses .data4, like i80.  Also, i86 and i386 now use the numeric
string without converting it to an integer and back to a string.

George Koehler 5301cceee3 Declare machine-dependent functions in mach/proto/ncg 
This breaks all machines because the declared return type void
disagrees with the implicit return type int (when I compile mach.c
with clang).  Unbreak i386, i80, i86, m68020, powerpc, vc4 by adding
the return types to mach.c.  We don't build any other machines; they
are broken since commit a46ee91 (May 19, 2013) declared void prolog()
and commit fd91851 (Nov 10, 2016) declared void mes(), with both
declarations in mach/proto/ncg/fillem.c.

Also fix mach/vc4/ncg/mach.c where type full is long, so fprintf()
must use "%ld" not "%d" to print full nlocals.

David Given fd91851005 Add enough return types to the K&R C that the ACK builds (on Linux) using clang 
now.

David Given f67c98e239 Distributions are a pain --- let's not bother any more. Instead, we just tag 
the repository and download a complete snapshot, old and ancient stuff and all.
